98. VERNONIA BLopceTri Small, FI. S. U.S. 1160. 1903 
Vernonia angustifolia pumila Chapman, Bot. Gaz. 3: 5. 1878. 
Stem slender, aie faintly striate, eaten or nearly so, simple 
or branching from the base, 2-6 dm. high; leaves numerous and 
crowded belo ow, ie and scattered above, the largest at or near the 
base of the stem, spreading or eae firm, linear or narrowly 
lanceolate, 4-8 cm. long, 3-6 mm. wide, obiiee or acute, entire or 
minutely denticulate, glabrous above, very sparsely short-pubescent 
beneath; upper leaves much smaller; inflorescence loose, irregular ; 
heads all peduncled, about 21-flowered, 8 mm. high at maturity; 
involucre broadly campanulate or Pee 5 mm. high; scales 
ew, appressed, very loosely and irregularly imbricated, lanceolate, 
acute or subacute, glabrous or nearly so, the exposed portion red 
or purple ; achenes 2.5 mm. long, sharply ribbed, pubescent in the 
furrows; pappus yellow, twice as long as the achenes 
Type locality : Pine EL Florida. 
Of the seven sheets in the herbarium of the New York Botanical 
Garden four have the narrow leaves and acute scales of the type, as 
characterized above. The other three, Small & Wilson 1878, Cur- 
tiss, and Small & Carter 771, have the lower leaves obtuse or even 
rounded at the apex, much broader and shorter, the length being 
only three to six times the width, and the scales sharply mucro- 
nate or even acuminate. Additional field study may prove this to 
be a distinct species. 
The use of Chapman’s varietal name for the species is prevented 
by the publication of the name V. pumila for an African species.
